(c1. m -a) This invention relates to improvementsin methods and apparatus for winding skeins of yarn.

The present invention has for'its 'principal object to provide improvedmethods and apparatus for winding skeins of yarn. v

Other objects and advantages of the invention will be apparent from thefollowing description and accompanying drawings which show'prefrredembodiments of the invention. s

' The means for carrying out the invention as shown in Figure 1comprises the reel or. swift indicated by reference character Imountedon the central shaft 2 which is supported in the frame II and driven bysuitable means which are not shown, The yarn A is directed to the reelor swift by the guide 4 carried by the traverse member comprising thebell crank having arms 5 and 6. and pivotally mounted on the frame at I.The traverse member is actuated by the linkl which is pivotallyconnected at one end to the arm I and at the other end to the engage thestop member.

gear 9. The gear 3 is driven by the gear l0 which is fixed tothe centralshaft 2. The gear 9, in rotating, reciprocates the link 8 and causes thetraverse member to move the thread guide back and forth across the faceof the reel or swift.

The connection of the link 8' with the gear 9 is shown more particularlyin Figures 2 and 3. The link is journaled at one side of the gear on theeccentric portion I2 of the pin I3 which is journaled in the gear 9. Theratchet wheel I4 is fixed on the pin on the other side of the gear. Thestar wheel I5 is pivotally mounted on the pin IS on the same side of thegear as the ratchet wheel. The star wheel has a hub portion II which.is-eccentric to the pin and on which is pivotally mountedthe pawl Ill.The spring member l9 urges the pawl into engagement with teeth on theratchet wheel. In order to prevent undue rotation of the ratchet wheel,brake means are provided comprising the spring clip 22 fastened to thegear by the screw 23 and having one end pressed against the face of theratchet wheel. The stop member 20 issupported 'on the pin 2|. inposition to contact the teeth on the star wheel and can be moved toinoperative position, when desired, by being swung r'ccates the link 8back and forth. The star wheel is carried around by the gear and theteeth As the teethof the star wheel are retarded by the stop member, thestar wheel is in effect rotated intermittently a part of 'arevolution'on the pin 16 relative to the gear for each revolution ofthe gear. Theeccentric hub of the star wheel in rotating about the pin 16 actuatesthe pawl which rotates the ratchet wheel. The ratchet wheel rotates thepin [3 and shifts the axis of the eccentric por- 1 tion relative to theaxis of the gear on which it is mounted. The effect of shifting the axisof the eccentric portion isto vary the length of stroke of the link andthe path of the thread guide back and forth across the face of the reelor swift and accordingly thepath of the yarn being wound on the reel.This is shown in Figure 7 where reference characters B, C, D,and E.

indicate that the distances that succeeding strands of yarn are placedapart on the reel vary during the winding operation.

- In the form of the invention shown in Figure 5 the length of thetraverse of the threadrguide across the face of the reel remainssubstantially the same, while the portion of the face of 'the reel voverwhich the thread guide traverses, changes continually during the windingoperation. This form as shown comprises the reel or swift 25 mounted onthe central shaft 26 which is supported in the frame 33 and driven bysuitable means which areunot shown. These parts are the same as thecorresponding parts shown in Figure 1. The yarn is directed to the reelor swift by the guide member 21 which is carried by the traverse member28. The traverse member and the link 29 are fixed to the rotatable shaft43. The traverse member is actuated by the link 3| which is pivotallyconnected at one end to the gear 32 and at the other end to the link 29.The gear 32 is driven by the gear 34 which is fixed to the central shaft26. The gear 32 in rotating reciprocates the link 3| and causes thetraverse member to move'the thread guide back and forth across the faceof the reel or swift. The link 3| is pivotally connected to the.

link 29 through the eccentric portion 36 of the pin 34 which ispivotally mounted near the end of the link 29. The ratchet 35 is fixedto the pin 34. The star wheel 49 is fixed to the pin 38 which ispivotally mounted on the link 2-9. The star wheel has an eccentric hubportion 39 on which.

- star wheel is carried back and forth on the link 29 and the teethengage the stop member. As the teeth of the star wheel are retarded bythe stop member the star wheel is in effect rotated a part of arevolution during each oscillation of the link 29. The eccentric hub ofthe star wheel in rotating actuates the pawl which rotates the ratchetwheel. The ratchet wheel rotates the pin 34 and shifts the axis of theeccentric portion 36 relative to-the link 29. The eccentric portion, inshifting its axis, moves the link 29 relative to the link 3|. The strokeof the link 3| and of the thread guide on the traverse member back andforth across the face of the reel remainssubstantially the same duringthe winding operation, however, the link 29 in shifting relative towhile the portion of the reel over which the thread guide traverses,changes continuously duringthe winding operation. This embodimentcomprises the reel or swift 45 mounted on the central shaft 46 which ,issupported in the frame 54 and driven by suitable means which are notshown. These parts are the same as the corresponding parts shown inFigures 1 and 5. The yarn is directed'to the reel or swiftby the guidemember 41 which is carried by the traverse mem-' ber comprising the bellcrank having the arms 49 and 49 which is pivotally mounted to rotateabout the shaft .65. The link 59 is mounted to pivot freely on the shaft65. The traverse memher is actuated by the link which is pivotallyconnected at one end to the gear 52 and at its other end to the link 59.The gear 52 is driven by the gear 53 which is fixed. to the shaft 46.The gear in rotating reciprocates the link 5| back and forth andoscillates'the link 59 about the shaft 65. The ratchet wheel 58 is fixedto the pin 66 that is pivotally mounted in the link 59. The pin has aneccentric portion 51 which engages the sides of the slot 56 in bellcrank arm 49; The star wheel 63 is fixed to the pin 62 which ispivotally mounted on the link 59. The star wheel has an eccentric hubportion 6| on which the pawl 69 is pivotally mounted. The pawl is heldin engagement with the teeth on the ratchet by means of the spring 59.The stop member 64 is pivotally supported on the frame in position tocontact the teeth on the star wheel and may be moved to an inoperativeposition out of the path of the teeth.

In the operation of this embodiment the gear 52 in rotating reciprocatesthe link 5| which oscillates the link 50 on the shaft 65. The eccen-.

tric portion 51 of the pin 66 carriedby the link 59 oscillates the arms48 and 49 of the bell crank about the shaft 65 and causes the threadguide to move back and forth across the face of the reel. The star wheelis carried back and forth as the link 59 is oscillated and the teethengage the stop member. As the teeth of the star wheel are retarded bythe stop member, the star wheel is in effect rotated a part of arevolution during each oscillation of the link. The eccentric hub of thestar wheel in rotating actuates the pawl which rotates the ratchetwheel. The ratchet wheel in rotating shifts the axis of the eccentricportion 51 of the pin which shifts the arms of the bell .crank relativeto the link 59. In this embodiment the length of the traverse of thethread guide across the face of the reel and the distance betweensucceeding strands of yarn indicated by reference characters F, G, H andI in Figure 8 remains the same while theportion of the reel over whichthe guide traverses continually changes during the winding operation.

In accordance with this invention, the thread guide is shifted, inaddition to the usual traverse movement, an amount sufficient thatsuccessive strands of yarn directed to the same portion of the reel arearranged side by side as shown in Figure 4.
